What is Xynaptic?

Xynaptic is a pay-per-call platform of 201 real-world data and intelligence services built for AI agents — and readable by humans. Official sources, fresh data, signed responses.

Your agent sends a request, pays the exact price in USDC through the x402 protocol, and receives structured JSON with proof. No account. No API key. No subscription. From $0.01 to $0.50 per call.

What it brings to your agents

The x402 flow in 4 steps

GET /v1/crypto-price
→ 402 Payment Required  { price: "$0.01", payTo: "0x…", networks: [base, polygon, solana] }
→ x402 payment signed + settled
→ 200 OK  { "BTC": { "usd": … }, "_proof": … }

Your first call in 60 seconds
